When I first think of sustainability, I think about longevity which I believe is possible when unwavering value is provided on a consistent basis... this is more so in the context of the idea of “sustainable communities”,with emphasis on human interactivity with a space or place.
In addition, when I think about sustainability, I think about design components which have grown in popularity and are becoming standard for many modern buildings. Features like, water reclamation roofing/plumbing, green roof, pv solar panels, etc.
A concept that i really love regarding sustainability.
I like hidden solar panels on flat roof buildings like this one.
The repurposing of old structures.
